Phone Line at Fault
Problem Description:
• Problems with print quality at the receiving fax, such as corrupt images, lines in the image,
white horizontal lines, missing rows or top/bottom cut off.
• When you test the Sending Fax and Receiving Fax you cannot reproduce the print quality
problem. The problem only occurs during faxing.
Most Likely Cause:
• Noise in the phone line, incoming call (call waiting), incorrect setup of dial type, line type,
reception mode or electrical interference.
Resolution:
• Check/setup the dial type, line type and reception mode.
• If the phone line is part of a DSL connection, check to see if a Splitter (Line Filter) is installed
or replace the Splitter.
• Disable Call Waiting if it is enabled.
• Check the telephone line for static or other noises.
• Remove any electronic equipment (i.e. televisions, microwaves, etc.), motorized devices or
wireless/broadcasting equipment that may be located near the fax machine. Electrical
interference from the equipment may degrade the telephone line condition.
